Definitions

  • Analog signals generated by various devices sucri as sensors are very often desired to be converted into corresponding digital signals because of the convenience and accuracy of digital signal processing.
  • An analog-to-digital (A/D) converter is a well-known electronic circuit that receives an analog input signal and produces a digital output signal. Thus, the digital output signal is produced based on samples of the analog input signal taken over time.
  • A/D converters are used to provide sequences of digital code representations of numbers in a chosen number base such that the numbers correspond to the amplitude value of sample portions of the analog signal input waveform with respect to a predetermined reference value.

Abstract

L'invention concerne un circuit de convertisseur analogique-numérique (A/D) doté de deux canaux séparés, couplés pour recevoir un signal d'entrée analogique simple, chacun des deux canaux comprenant un moyen de conversion d'un signal d'entrée analogique en un signal numérique à des moments d'échantillonnage respectifs qui sont réglables de façon qu'ils soient sensiblement simultanés. L'invention concerne de plus un moyen réglage du gain des deux canaux de sorte qu'ils soient différents selon un facteur prédéterminé, un moyen de détection de débordement d'un canal dans un des deux canaux possédant un gain plus élevé ; et un moyen de réunion des deux canaux en un flot de sortie continu.
